DETAILED DESCRIPTION

As described herein, an aspect of the present invention includes policy-based elastic cloud-driven task execution. An example embodiment of the invention includes a process or agent residing within a cloud computing architecture enabled to effectuate a system or enterprise policy to any number of remote clients through the provisioning of particular sets of virtual machines (VMs). In the same fashion, the process or agent can be location-aware of the dynamic state of each remote client and able to adjust virtual machine provisioning based on this knowledge.

By way of illustration, an example scenario for policy driven desktop action can include the receipt of an e-mail, or file, whose extension is unknown to the user's VM operating environment. An embodiment of the invention can discover the appropriate application which can interpret this file, and securely drive or assist the user to open and execute the file within a compartmentalized environment, for example, based on the user's policy. The policy, by way of example, can be related to, but not limited to, security, mobility, or any appropriate relevant context.

Accordingly and as further detailed herein, aspects of the invention accelerate and simplify a customer experience with new extensions in the desktop service interaction, and also increase the functional scope of the desktop experience.

At least one embodiment of the invention includes assisting a user (end user for desktops or admin for servers) to create an unknown task handling a policy, which can be related to, but not limited to, resource capacity, security, mobility, license, cost, custom context, etc. Additionally, a federated registry can be built that includes applications and services relationships as well as mappings to contexts. Matching application(s)/service(s) can be discovered which can run tasks unrecognized by the original operating system (OS) or application (app) based on a policy.

Also, an aspect of the invention includes using a rating system for open source resources (for example, for new file extensions) and assisting with an ordered list of selected relevant app/service matches. Further, at least one embodiment of the invention includes transparently and compliantly driving or assisting the run, use and termination of a selected app/service within a controlled environment based on a policy (for example, start a new VM and run app).

Additionally, by way of example, an embodiment of the invention can include facilitating a charge depending on policy, user type, license, etc., as well as enabling usage limitations based on cost (for example, usage limited up to $5 charge). Further, the app/service used to handle the unknown task can be subsequently rated.

As such, aspects of the invention include discovering applications and application execution tasks when such items are necessary to a user and unknown. Also, as described herein, an aspect of the invention includes managing a lifecycle of an application execution from start to end in a remote virtual machine based on policies that include the user's preferences for performance, security, etc.

FIG. 1 is a diagram illustrating system architecture, according to an embodiment of the present invention. By way of illustration, FIG. 1 depicts a policy store or database 102, a policy engine 104, a connection brokering agent component 106 and agents 108. Additionally, FIG. 1 depicts a client device 110, a service dispatcher component 112 and a service 114 (a web application, a shared server, a virtual client, a stream server, etc.).

As noted, in an example embodiment of the invention, the system includes one or more client devices which provide a user interface, a policy database to store the policy statements, a policy engine to match the policy statements against the current service request, a set of agents to gather the situational and service request aspects of the action, one or more service providers to deploy the service if required, a connection brokering agent to receive the service requests and dispatch the service and connection actions to fulfill the request, and a cloud which provides all the computing resources with the exception of the client device.

As also in accordance with an example embodiment of the invention, such a system can operate as follows. A user requests a service, for example, by clicking on an icon displayed on the client device or typing a command into the client device. The client device relays this request to the connection brokering agent. The connection S brokering agent relays aspects of the request (client type, specific request, user identity, etc.) to the policy engine to resolve a way to service the request. The policy engine consults the policy database (as well as optionally one or more agents to assess the details of the situation) and determines the best/desired match between the situation and the methods for providing the service. Additionally, the policy engine returns the suggested service method, and possibly several alternatives to the connection brokering agent.

The connection brokering agent dispatches the service, which might, for example, include streaming the application for the service to the device, launching a server or remote client to execute the service for the client, selecting a shared server which is running the request service, or launching the application instance which is already installed on the client device.

Additionally, the connection brokering agent responds to the client device with the details of how to provide the user interface to the service, which might, for example, include launching the application locally and displaying the user interface from the local instance, streaming the application from a specified stream server and either installing the application locally or running locally from the stream, launching a remote presents client and attaching to the appropriate remote client, server, or shared server to display the service user interface, or launching a web browser to a uniform resource locator (URL) which provides the requested service as a web application.

FIG. 2 is a diagram illustrating a workflow for policy-based elastic cloud-driven task execution, according to an embodiment of the present invention. Step 202 includes creating and/or updating a policy (for example, contexts and tasks). Step 204 includes creating and/or updating a rated registry (for example, a context or services). Unknown task 206 is the starting point of the “solve the task” flow. In the illustration of FIG. 2, there are multiple flows, including the set up/update of the environment. Step 208 includes discovering matching application(s) and service(s). Step 210 includes using a rating system to prioritize matching application(s)/service(s). Step 212 includes driving or assisting the run, use and termination of a selected/prioritized application/service match to handle the unknown task 206. Step 214 includes rating the selected application/service match, and step 216 includes charging. Charging can include, for instance, providing an invoice resulting from billing the service that provided the task.

As detailed herein, choosing a desired or optimum approach for delivering a specific function at a specific time to a specific location and device is dependent on the context and any policies which govern the use to meet risk and privacy guidelines.

In accordance with at least one embodiment of the invention, performing a computing or communications tasks can be dependent of many aspects of the context such as, for example, the user's current location and interaction device (device performance, network connectivity, bandwidth, security, etc.), the type and location of the data items which the user needs to manipulate (file type, file size, home location, security restrictions, etc.), the specific operation the user need to perform on the data (view only—whole document or snippet, edit document, stream document, etc.) and the content of the document itself (steamed media, medical diagnostic image, privacy restricted information, etc.).

Achieving a desired or optimal performance and user experience for a given interaction can also be dependent such aspects. Likewise, there can be many delivery modes available (web app, locally installed app, virtual desktop, application virtualization, etc.), and each of these delivery modes has a specific set of capabilities and challenges.

An aspect of the invention includes pulling together some or all of the above-noted aspects for a specific session and making a context-aware choice of how best to deliver the experience given the situation. Accordingly, in an aspect of the invention, there is a deterministic aspect, given the offline mapping between tasks and potential execution environments for the task, as well as the runtime mapping between a given context and the user's policies. There is also a dynamic aspect, given only few execution environments are selected based on the current policies in place for each user, the ratings, etc.

Examples of contexts include current location, current quality of bandwidth, devices, desktop, mobile, etc. Additionally, the term “context-aware” is used to describe a model of computing in which users interact with different mobile and stationary computers and classify a context-aware system as one that can adapt according to its location of use, the collection of nearby people and objects, and according to the changes of those objects over time.

Organized contexts can help applications to find information needed by comparing a current context to a policy or model. By way of example, a privacy setting may be enforced by storing sensitive context information on the user's personal device and not sharing that information with applications running on another device, while more public information in the hierarchy may be stored in another location, such as public storage or a cloud device, where the information can be shared with applications running in a variety of locations.

As detailed herein, policy can include considerations of performance, security, quality of experience, optimization type (cost for user, capacity for mobile, etc.), etc. With respect to performance, for example, with a user querying a particular file extension and subsequently needing to execute the related application, an aspect of the invention includes evaluating the resource utilization on the local operating environment and determining if additional virtualized resources are needed in an on-demand fashion. Accordingly, that particular application is opened in a performance container that does not conflict with the resources Of the user's local environment.

With respect to security, for example, a user may need to access a potentially unsecure e-mail attachment or file and ensure that it does not corrupt the primary virtual or primary local operating environment. Accordingly, an aspect of the invention includes opening the file in a secure container. Container, as used herein, refers to an environment (application. VM, etc.) that is completely controlled with respect to the assumed security level.

Also, with respect to quality of experience, for example, network location-awareness for a user's device can provide information on the link state that can allow the database directory to enhance how the end user device accesses the application that is tied to the file extension.

Another aspect of the invention includes providing extended relationships/mapping. In at least one embodiment of the invention, this aspect requires a database structure (or file maps or directory of services) listing all known file extensions and the applications which support those (at least within the context of the enterprise or organization to which the user belongs). This might include, for example, listing all known applications for which an enterprise or organization has paid access. A database such as noted above may also contain, in an example embodiment of the invention, relevant metadata regarding the file extension and application to which it corresponds. This may include useful information for understanding a desired method in which to provision the app to the end user device (for example, if using a mobile phone decision), Universal Description, Discovery, and Integration (UDDI) for WebServices related applications, CromOS like related applications on metal, etc.

At least one embodiment of the invention also includes a decision daemon (or analogous process) which runs within the operating environment of the user's device and intelligently senses when elasticity is required upon query of a particular file extension and subsequent calling of the corresponding application. With respect to elasticity, if the file to be executed upon is too large or involves opening an application requiring resources beyond the current limits in the policy (for example, CPU, RAM, number of applications, number of processes, etc.). the elasticity refers to the ability to dynamically find additional resources to match the requirements.

In connection with execution of an example embodiment of the invention, in response to changing conditions, there can be several options for adjustment action (all of which can be chosen based on global policy). For example, capacity of an existing desktop VM can be extended by increasing its resource share of the underlying physical server. Examples include increasing memory size, number of central processing unit (CPU) cores, or storage. This option allows for improvement in user experience.

Another option includes starting a remote application instead of local execution. The application executes on a remote server with the screen and keyboard and mouse events forwarded to the original desktop VM, or, directly to the end user device. Screen (raster) level composition can occur at the end user device or at the VM.

Yet another option includes launching a dedicated virtual machine and starting an application in this newly launched VM. Such an option allows growth of capacity allocated to a desktop user by horizontal scaling, as well as isolating the execution. Additionally, another option includes executing the required task using a web service and appropriately converting the result to be presented in desktop environment. Yet another option includes streaming application binary from the streaming server and executing locally (either on end-point, or on the VM).

As described herein, an example embodiment of the invention can include a charge feature. Such an embodiment can include displaying a payment option for a per-use fee next to each file extension when a query is made. The software user may look-up the file extension needing access to the app to open it, but will be presented with a payment option to have the app streamed for his/her use for a temporary period. Additionally, such an example embodiment can include enabling a usage limitation based on cost (by way merely of example, “usage limited up to $5 charge”).

FIG. 3 is a now diagram illustrating techniques for cloud-driven application execution, according to an embodiment of the present invention. Step 302 includes determining a plurality of attributes of a failed application, wherein the plurality of attributes comprises at least one policy context attribute and at least one context attribute. Context attributes can include, for example, a user location, an interaction device attribute, a data type, a data location, a specific operation on data, and a document content attribute.

Step 304 includes correlating each of the plurality of attributes to at least one alternative asset, wherein the at least one alternative asset is a part of an environment on which the failed application can be executed.

Step 306 includes using the plurality of attributes correlated to the at least one alternative asset to identify an alternative asset set of at least one alternative asset (for example, in a registry database), wherein the alternative asset set is capable of enabling an alternative environment on which to execute the failed application.

Step 308 includes provisioning the at least one alternative asset in the alternative asset set from at least one cloud network to create the alternative environment on which the failed application is executed. Creating the alternative environment on which the failed application is executed can include, for example, streaming the application to a client device, launching a server or remote client to execute the application for a client, selecting a shared server execute the application, or launching an instance of the application which is already installed on a client device.

Additionally, an embodiment of the invention can further include providing a user interface to the application. Providing a user interface to the application can include, for example, launching the application locally and displaying the user interface from a local instance of the application, streaming the application from a specified stream server and installing the application locally or executing the application locally from the stream, launching a remote presents client and attaching to an appropriate remote client, server, or shared server to display the user interface, or launching a web browser to a uniform resource locator which provides the application as a web application.
